This file describes the setup of the AVR gcc environment and the
modifications in btnode-hackfest-20021104.bin.tar.gz to have
a Windows98/2000 command line version of the BT Smart-Its Development
environment.

0. Setup (Win2000 tested, but Win98 seems to be analog)

0.1 

  - Setup the compiler by copying 'avrgcc' into a directory of your choice
  - change to 'avrgcc\avrfreaks\win2000' and modify 'avrmake2.bat' (not 'avrmake.bat')
    (for Win98 modify 'avrgcc\avrfreaks\gcc_cmp.bat')
  
    - set AVR to the directory where you have avrgcc installed
    - set GNUAVR to the directory where you have avrgcc installed
    - let CC unchanged
    - set PATH to the bin directory of the compiler directory
    - set BTNODE_INSTALL_DIR to the directory, where you will 
      unpack btnode-hackfest-20021104.bin.tar.gz
    - copy 'avrmake.bat' and 'avrmake2.bat' to a directory where a path points to
      ( for example: copy to D:\WINNT )
      
      ( for Win98 copy 'avrgcc\avrfreaks\gcc_cmp.bat' and 'avrgcc\avrfreaks\gcc_cmp2.bat' to such a directory )
            
0.2      

  - unpack btnode-hackfest-20021104.bin.tar.gz to $(BTNODE_INSTALL_DIR)


For Makefile modifications all paths start from $(BTNODE_INSTALL_DIR)

1. Makefile modifications

1.1 Modify $(BTNODE_INSTALL_DIR)/examples/smart-its/Makefile

  replace line 
    
    SUBDIRS = avr128 linux
  
  with
  
    SUBDIRS = avr128

3. Compile $(BTNODE_INSTALL_DIR)/examples/smart-its/Makefile

3.1

   - call the script 'avrmake.bat' in the directory above (have a look on "Hints" below)
   - compiled files are stored in $(BTNODE_INSTALL_DIR)/examples/smart-its/avr128
   
3.2

   - clean it up: call 'avrmake.bat allclean' $(BTNODE_INSTALL_DIR)/examples/smart-its
     (this deletes all compiled and intermediated files)
     

Hints:

During compilation you will see warnings of makedepend saying:
 #error "Don't know how to make helloworld for non avr103 and avr128 platforms."
or
 #error "This example depends on the dispatcher but the dispatcher is configured out. see include/smart-its.h"

Don't worry. It's a bug in makedepend. To avoid it just search through all files in 
$(BTNODE_INSTALL_DIR) for these messages and insert a whitespace character before each (basicially 
you indent them by one whitespace character.)
